From: Phil Edworthy Date: Thu, 2 Jun 2011 22:15:27 +0000 (+0000) Subject: sh: Add support for SH2A freestanding build X-Git-Tag: v2011.09-rc1~72^2~6 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=eeb84df6e43212a31e96402788ec9b3e39a399a6;p=oweals%2Fu-boot.git sh: Add support for SH2A freestanding build SH2A toolchains often only provide an fdpic version of libgcc. This can't be used with bare-metal software like U-Boot, so this patch provides the necessary functions extracted from libgcc.
